ROTARY ENGBNE.

SPECIFICATION forming part of Letters Patent No. 344,019, dated .Tune 22, 1886.

Application filed April 17, 1886. Serial No. 199,164. (No model.)

To @ZZ whom it may concern:

Be it known that we, GEORGE E. TonivER, HENDERSON W. PoUNDs'roNE, and ELI SoHorE, citizens of the United States, residing at Newport, in the county of Barton and State of Missouri, have invented certain new and useful Improvements in Rotary Engines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and letters of reference marked thereon, which form a part of this specification, and in which- Figure l is avertical longitudinal section of a rot-ary engine constructed in accordance with our invention. Fig. 2 is a vertical section of the same at right angles to-Fig.1. Fig. 3 is a side elevation, with parts broken away to better show the construction and arrangement of some of the parts. Fig. 11 is a perspective view of the packing-ring, Fig. 5, perspective details more particularly hereinafter referred to.

This invention relates to rotary engines, and is designed as an improvement upon the device shown and described in Letters Patent No. 327,621, issued October 6, 1885, to George E. Toliver; and it consists in the peculiar combinationsand the novel construction, arrangement, and adaptation of parts, all as here-` inafter more fully described, shown in the drawings, and particularly pointed out in the claims.

Referring by letter to the said drawings, A indicates a suitable base; B, the case-ring; G, the steam-wheel; D, the shaft, which is provided with a pulley of the ordinary construction (not shown) for communicating power from said shaft.

E is the governor, and F the oil-cups.

All of the above-mentioned parts are of well-known construction, except as hereinafter explained.

The steam-wheel C is provided with a peripheral channel, c, and slots c', in which work the valves C', provided with necks or projections c.

F F are segmental blocks pivoted upon the necks or projections c oi' the valves, and regulating the movement of the valves by means of engagement with the eccentric grooves F, formed in the cylinder-heads, and. within which grooves the blocks travel.

In rotaryV engines of former constructiomin which the projections or pins c travel within the eccentric grooves and no blocks have been provided, it has been found that, owing to The case-ringis constructed in two sections, i

as shown.

G is the steam-chest, provided with an upper and lower opening or steam way or inlet, d d, through which the steam enters the peripheral channel in the wheel. The openings d d are controlled by means of a sliding valve, d, operated by means of the lever II, to which it is connected by means of the crank-lever mechanism e, which may be of any suitable construction adapted to such use.

The section of the case-ring which is upon the side of the wheel opposite to the steam- `inlets last above described is provided at points above and below the center of the same with openings ff', which communicate by means of channels g g', formed within the body ofthe case-ring, with an exhaust-steam chest, G', the steam outlets being controlled by means of a sliding valve, e', in all respects similar in construction and operation to the steam-valve d, described in connection with the steam-chest Gr.

Each of the slide-valves is provided upon its front face withlugs b, between which the valverod b passes. This end of the valve-rod is screw-threaded, and is provided upon opposite sidesof said lugs with adjusting-nuts b and b, as shown.

The case-ring B is` provided near eachedge IOO with a peripheral channel, B', which, when the parts are in place, is coincident with the pe ripheral liange'B" of the steam-wheel. In each oi these channels is placed a packing-rin g, B', preferably of spring metal. Between thesteaniy' inlet ports d d' is a packing-block consisting of the parts hh' h", the part 7L" forming a stop, against which the ends of the packing-ring B'" abut, and the whole serving to close the pleripheral channel in the steam-wheel between the two ports d d' and prevent the passage of steam in the wrong direction.

In operation, with the valves and ports arranged relatively to each as shown in Fig. l, [5 the steam enters at d into the peripheral channel of the steam-wheel, and exerts its force against the valves therein to force the wheel in the direction of the arrows in Fig. l. After passing the exhaust-portf, the valves are drawn in by means of they engagement of the segmental blocks with the cam-grooves in thecylinder-heads, and the steam exhausts through theportf and the channel g. By reversing the lever the position of the slide-valves is ing the lowereXhanst-port, the steam entering at d', and, by means ofthe packing-block h h' h", being forced toflow in the direction of the arrow in Fig. 3, thus forcing the wheel in the direction of said arrow in said figure, or in the opposite direction to that in which it was traveling before thel position of the valves was changed. Thus it will be seen that a mere reversal of the lever reverses the direction of travel of the wheel, simultaneously moving the valves in opposite directions.

We have shown what at the present time we consider the best form of carrying out our invention, but do not wish to confine ourselves to the form shown, as it is evident that the samemay be varied to a certain extent without departing from the spirit of our invention.

We` are aware that rotary engines have been provided with valves having rollers working ineam-grooves in the cylinder-heads, and we make no claim thereto.

We deem our segmental blocks a `decided* V changed, opening thelower inlet-port and clos- Having thus described our invention land set forth its merits, what we claim to be new, and desire to secure by Letters Patent, is-

l. The combination, with the cylinder-heads provided with cam-grooves, of a steam-wheel Y provided with valves having segmental blocks fitting in said grooves, substantially as described.

2. The combination, with the cylinder-heads provided with camgroovcs, of a steam-wheel, valves carried thereby and provided with necks extending upon opposite sides thereof, and segmental blocks pivoted on said necks and engaging with said cam-grooves in the cylinder-heads, substantially as described.

3. In a rotary engine, the combination, with a valve, of a segmental block on the neck of said valve and made in sections, substantially 7o as described, and for the purpose specified.

4. In a rotaryy engine, a segmental block composed of the section it, having opening to receive the neck of the valve, the section le', provided with pins a, and the packing a', in- 75 serted between said sections 7c 7c', substantially as and for the purpose specified.

5. In a rotary engine, the combination, with the case-ring provided with aperipheral chan- Y nel, B', and the steanrwheel provided with a 8o peripheral iiange, B", in the ports d d', and a packing-block between said ports, of a springmetal packing-ring inserted in said channel with its ends abutting against said block, substantially as described.

6. In a rotary engine, the combination, with the case-ring provided'with peripheral channels B', and the steam-wheel C, provided with the peripheral flanges B", forminga peripheral 'channel, as described, of the packingblock 93 consisting of the parts hh'h", and the packingring B'", inserted in theperipheral channel of the case-ring, with its ends abutting against the part h" of said packing-block, as set forth.

In testimony whereof we aflix our signatures in presence of two witnesses.
